ARTHUR IV M. FREEMAN, OF NEWARK, NEW JERSEY.

HAME-BENDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 498,469, dated May 30,1893.

Application filed July 12, 1892. Serial No. 439,753. (No model.)

To all whom it may concern.-

Be it known that I, ARTHUR WM'. FREEMAN, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Hams-Bending Machines;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same,referencebeing hadto the accompanying drawings, and to letters of reference markedthereon,which form a part of this specification.

The object of this invention is to facilitate the operation of bendingand fitting hames to collars, and to secure other advantageous results,hereinafter referred to.

The invention consists in the improved hame bending machine and in thearrangement and combination of the several parts thereof, as herein setforth and finallypointed out in the claims.

Referring to the accompanying drawings,

in which similar letters of reference indicate corresponding parts ineach of the figures where they occur, Figure 1. represents, a top planview of a hame bending machine embodying my improvements and Fig. 2 is atransverse section taken through line at. of the same.

In said drawings A. indicates a bed plate, upon which the working partsof the machine are mounted or of which they form a part,

provided with apertures b. to admit the pas-' sage of screws or boltsfor fastening it to a suitable platform orsupport. Mounted upon said bedplate are blocks B. which may be either movable or stationary butpreferably movable, and a block 0. movable longitudinally and operated,in the present instance by means of a screw, D. the inner end of whichis fitted and works in a socket, in said block 0, wherein it is held bymeans of a pin or key 0, which registers with an annular groove 0'.formed in said inner end of the screw, as indicated in Fig. 2, and bydotted lines in Fig. 1. Said screw works in athreaded hub, E, formed ormounted upon said bed plate; and in said hub, as also in the block 0, isformed an aperture, f, to admit of the introduction of a lubricant, aswill be understood. Said blocksB and Care also provided on the bottomwith tongues, g, as indicated in Fig. 2, which work incorrespondinggrooves or slots h and t, in the bed plate and are held inposition by means of set-screws j and hand bars, Z, as indicated in thedrawings. They are also provided with cushions F and G, which are made,preferably, of hard wood, and are secured in sockets formed in the endsof the blocks by means of set-screws, s, so as to be removable andreplaced by others at pleasure.

Instead of the wood cushions the faces of the blocks may be covered withleather, rawhide, or other material, softer than iron, the object beingto avoid marring the hames in the operation of bending, and moreespecially when bending hames which have been plated, galvanized, orjapanned, as is frequently the case. The faces of the blocks orcushions, as will be observed, are made slightly convex, as a furthermeans to the same end.

The operation of bending is as follows:- The hames are first placed inposition between the blocks 13 and G, and are then bent by the pressureexerted thereon by turning up the screw D; the hames being movedlongitudinallyfrom time to time during the operation until they areproperly fitted to the collar; the said blocks B, may also be adjustedfarther from or toward one another, as the circumstancesof the case mayrequire, as will be readily understood.

In cases where the bonding is uniform or no adjustment of the blocks Bis required they may be permanently secured to or be cast integral withthe bed plate. The form of the latter is not material and may be changedin this respect as desired. It willbe evident, also, that a lever or cammay be substituted for the screw, to operate the block, 0.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is

1. In a hame bending machine, the combination, with a flat bed plate, ofbearing and pressure blocks secured thereto, each of said blocks beingprovided with a recess in its front or operating end, and the pressureblock being located opposite to and intermediate the bearing blocks, acushion for each block having a stem for securing it in the socket ofthe block, and also having a rounded operating surface, a" set screw ineach block for engaging the stem of the cushion and means for moving thepressure block between the bearing blocks, whereby a hame placed uponthe bed plate may be bent into the desired shape, substantially as setforth.

2. In a hame bending machine, the combination, With a fiat topped bedplate, having recesses in its under surface and a threaded hub upon itsupper surface, said plate being further provided with means for securingit in position and with three slots, two of which slots aresubstantially in line with each other and the other slot is located atright angles I 5 thereto a block adj ustably secured in each of theslots, a bar and a set screw for each block,

ARTHUR \VM. FREEMAN.
